Fig. 4From: Protein profile analysis of Jilin white goose testicles at different stages of the laying cycle by DIA strategyFunction classification in Clusters of Orthologous Groups of Proteins (COG). (All proteins were aligned to the COG database to predict possible functions. A total of 3013 putative proteins were functionally classified into 25 groups. Capital letters on the X-axis shows the COG categories as listed on the right of the histogram and the Y- axis shows the number of matched proteins)Back to article page
